Princeton Power Systems (PPS) has implemented an energy-storage system at BMW Group's technology office in Mountain View, Calif. The system uses PPS' new demand-response inverter (DRI) in an integrated system.

The system, which consists of a 100 kW DRI and 30 kWh lithium-ion batteries, will be used to store renewable energy from the on-site solar array, reduce peak electricity demand and demonstrate DC fast-charging technology for electric vehicles.

Months after the U.S. Environmental Protection Agency released its Clean Power Plan, which will create new regulations for existing power plants, the agency says it has received loads of feedback to consider.
